Re: [xsl] Using xsl:iterate inside <xsl:for-each-group> xslt 3.0

["Terry Ofner tdofner@xxxxxxxxx" <xsl-list-service@xxxxxxxxxxxxxxxxxxxxxx>]

Hmm. The map:merge appears to fiddle with the ?letter and the ?term. It
appears that the position() is coming from the $groups map. Not sure why the
letter is stuck on S and the term on sentence. Do I need an argument within
the map merge to tell how to merge the two?

<xsl:iterate select="for $p in p[@class = 'nl'] return $groups !
map:merge(($groups, map { 'p' : $p }))">

                        <xsl:text>&#10;</xsl:text>
                        <write_choice  spanNum="{position() - 1}"
letter="{?letter}"
                            term="{?term}" ans="{?p}"/>
 </xsl:iterate>

Output.

<write_choice spanNum="0" letter="S" term="sentence" ans="&#x9;1.&#x9;Sent the
package to her yesterday."/>
<write_choice spanNum="1" letter="S" term="sentence" ans="&#x9;1.&#x9;Sent the
package to her yesterday."/>
<write_choice spanNum="2" letter="S" term="sentence" ans="&#x9;2.&#x9;A
history teacher at the middle school."/>
<write_choice spanNum="3" letter="S" term="sentence" ans="&#x9;2.&#x9;A
history teacher at the middle school."/>
<write_choice spanNum="4" letter="S" term="sentence" ans="&#x9;3.&#x9;Roberto
works on Saturday afternoons."/>
<write_choice spanNum="5" letter="S" term="sentence" ans="&#x9;3.&#x9;Roberto
works on Saturday afternoons.b/>



I did experiment a bit with map:merge by creating another variable / map.

<xsl:variable name="answers" as="map(xs:string, xs:anyAtomicType)*">
                    <xsl:for-each select="p[@class='nl']">
                        <xsl:variable name="item">
                            <xsl:analyze-string select="."
regex="\t\t?(\d\d?)\.\t">
                                <xsl:matching-substring>
                                    <xsl:value-of select="regex-group(1)"/>
                                </xsl:matching-substring>
                            </xsl:analyze-string>
                        </xsl:variable>
                       <xsl:sequence select="map {'num':
$item}"></xsl:sequence>
                    </xsl:for-each>
                </xsl:variable>

With this iterate

<xsl:iterate select="p[@class='nl'] ! map:merge(($groups, $answers),
map{'duplicates':'combine'})">
                        <xsl:text>&#10;</xsl:text>
                        <write_choice  spanNum="{position() - 1}"
pNum="{?num}" letter="{?letter}"
                            term="{?term}"/>

                    </xsl:iterate>

I get the following output in which the sequence inside my $answer map donbt
work as I planned but I get all the letters and terms.

<write_choice spanNum="0" pNum="1 2 3 4 5 6 7 8 9 10 11 12 13 14 15" letter="S
F" term="sentence fragment"/>
<write_choice spanNum="1" pNum="1 2 3 4 5 6 7 8 9 10 11 12 13 14 15" letter="S
F" term="sentence fragment"/>
<write_choice spanNum="2" pNum="1 2 3 4 5 6 7 8 9 10 11 12 13 14 15" letter="S
F" term="sentence fragment"/>
<write_choice spanNum="3" pNum="1 2 3 4 5 6 7 8 9 10 11 12 13 14 15" letter="S
F" term="sentence fragment"/>
<write_choice spanNum="4" pNum="1 2 3 4 5 6 7 8 9 10 11 12 13 14 15" letter="S
F" term="sentence fragmentb/>
